Patent number: 12409102Abstract: Examples of the disclosure are directed to adjustable back plates or backboards for a mechanical compression device to accommodate different patient sizes and/or for ease of storage. Examples of the disclosure includes back plates that can be folded, pieced together, or otherwise have a variable distance between connectors that attach to legs of a chest compression device. Examples also include back plates which may have two sides, such as an adult patient side and a pediatric patient side, to accommodate different patient sizes.Type: GrantFiled: October 28, 2021Date of Patent: September 9, 2025Assignee: PHYSIO-CONTROL, INC.Inventors: Marcus Ehrstedt, Thomas Falk, Anders Nilsson, Tyson Taylor, David Linville, Eric Sandrup, Jonas Lagerstrom, Anders Jeppsson, Sara Lindroth, Fredrik Arnwald

Publication number: 20250186303Abstract: A CPR machine (100) is configured to perform, on a patient's (182) chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A force sensing system (149) may sense a compression force, and the driving can be adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected.Type: ApplicationFiled: January 16, 2025Publication date: June 12, 2025Applicant: PHYSIO-CONTROL, INC.Inventors: Anders Nilsson, Jonas Lagerström, Bo Mellberg, Anders Jeppsson, Marcus Ehrstedt, Bjarne Madsen Härdig, Fredrik Arnwald, Erik von Schenck, Paul Rasmusson, Sara Lindroth, Fred Chapman, Ryan Landon, Mitchell A.

Patent number: 10117804Abstract: A CPR chest compression machine includes a retention structure configured to retain a patient's body, and a compression mechanism configured to perform automatically CPR compressions to the patient's chest. The CPR machine also includes a camera coupled to the retention structure or to the compression mechanism. The camera has a field of view that spans at least a certain portion of the patient's body, and is configured to acquire an image of what is spanned by its field of view. The image may be stored in a memory, displayed, transmitted, analyzed to diagnose the patient, detect shifting of the patient within the CPR machine, etc.Type: GrantFiled: March 9, 2015Date of Patent: November 6, 2018Inventors: Anders Nilsson, Jonas Lagerstrom, Bo Mellberg, Anders Jeppsson, Marcus Ehrstedt, Bjarne Madsen Hardig, Fredrik Arnwald, Erik von Schenck, Paul Rasmusson, Sara Lindroth, Gregory T.
